Question
Design Shannon Fano algorithm and Hoffman algorithm for your set of symbols.
(show all the details).
Solution
Sure, let's start with the Shannon-Fano Algorithm:
-
First, we need to have a set of symbols with their corresponding frequencies or probabilities. Let's assume we have the following set of symbols: A, B, C, D, E with frequencies 15, 7, 6, 6, 5 respectively.
-
Sort the symbols according to their frequencies. The symbol with the highest frequency comes first.
-
Divide the set into two parts, where the total count of frequencies is approximately equal in both parts.
-
Assign '0' to the first part and '1' to the second part.
-
Repeat the process for each part until you get to individual symbols.
-
The Shannon-Fano code for a symbol is the string of binary digits you get by concatenating the '0's and '1's assigned from the top of the symbol set to the symbol.
Now, let's move on to the Huffman Algorithm:
-
Again, we start with the same set of symbols and their frequencies.
-
Create a node for each symbol and add them to the priority queue.
-
While there is more than one node in the queue:
- Remove the two nodes of highest priority (lowest probability) from the queue
- Create a new node with these two nodes as children and with probability equal to the sum of the two nodes' probabilities.
- Add the new node to the queue.
-
The remaining node is the root node and the Huffman tree is complete.
-
Traverse the constructed binary tree from the root to leaves. At each node, if we move to the left child, we append a '0' to the code. If we move to the right child, we append a '1' to the code. The Huffman code for a symbol is the string of binary digits you get when you reach the leaf node for the symbol.
Please note that both algorithms aim to minimize the average length of the codes, but Huffman's algorithm guarantees an optimal solution.
